Metro East Sun

Property owners in O’Fallon paid nearly 2.4 percent of the value of their homes in taxes last year. That’s nearly two times the national average, according to an LGIS analysis of real estate sales data in St. Clair County from Jan 1. to June 30.

Local Government Information Service (LGIS) publishes the Metro East Sun.

O’Fallon, population 29,031, recorded a median sale price of $185,000, based on data from the 207 properties sold during the first half of 2018. In 2017, homeowners paid a median property tax bill of $4,355, according county tax data from the St. Clair County Assessment Office.

That’s 2.35 percent of the community’s median home value. In the U.S., the average effective property tax rate is 1.19 percent.

Put another way: a $185,000 home in Indiana, where the effective rate is 0.89 percent, would have a property tax bill of about $1,647, or more than $2,700 less per year.

The analysis, including 19 St. Clair County communities with more than five sales since January, shows homeowners in Cahokia, East St. Louis, and Centreville pay the highest tax rates, each clocking in with effective rates of 4 percent or higher. 

Fairmont and New Athens have rates higher than 2.75 percent.

Rates in Millstadt and Belleville are 2.5 percent or higher — about average in Illinois but two times the national average. 

Illinois homeowners pay the second-highest property tax in the country with an effective median rate of 2.32 percent, just behind those in New Jersey's (2.28 percent).
